What's the first thing you'll do after you get "Get Famous"?

Start a new game and save all existing lots to My Library in case I want to put them back.
Experiment with the terrain tools and building stuff.
Stuff my built lots and the in-game ones with my own Pack items and save good ones to My Library for future use.

This will possibly keep me occupied for a couple of weeks and then I might start on actually playing. :)
